Hey guys, Old thread I know, but has any of you ever found a solution or a work around to this issue? I am deep in the NX system and still love both my NX1 and NX500 but this issue always keeps presenting itself on my NX1, apparently at random (some videos are perfectly fine, some others present the flickering issue, with no change in settings or scene whatsoever). Thanks and happy holidays, Pier
